` TRAIN-STOP. i

"Application led August 3, 1920. Serial No. 400,929.

T0 all whom it may concern:

`Be it knownthat 1, FRANK C. HANEY, a citizen of the United States, residing at Dayton, in the county of "Montgomeryand State of Ohio,f`have` invented new and useful Improvements in Train-Stops, of `which the following is a specification.

`This invention relates to automatically operated speedA regulatingand stopping de-` vices forrailroad trains.

An obj ect of the invention is the provision of a device which is adjustable toprevent the speed of a trainfrom exceeding a predetermined limit and for stopping a train inthe event ofasignal being set at danger.

Another object is the provision of a device which is carried by the locomotive for regulating the throttle 'valve and the `air valve, the said "device `being `operated by f a track device which is capable ofadjustment to determine thelimit of speed and to` operate the valve of the air brake.

@ther objects and advantages of the in vention will appear as the following description is read in connection with the accompanying drawings. i

Referring to the drawings ndetail, whereinlike :characters of reference denote correspending` parts, the invention includes a 1 locomotive carried device `which is designated `in its entirety by the reference character 10 and a track device `which is` shown at 1l and used for the operation of the locomotive carried device. i

`The `locomotive device 10 comprises agevernor 12 which is herein shown asl of the centrifugal type and which is mountedfor operation upon `a vertically disposed shaft 13,`mounted in suitable bearings Maand 15 provided in or carriedby the locomotive frame. The shaft 13 `has `secured upon one end a gear 16, which is driven by` a pinion 17, the latterbeing mounted upon one end of a shaft 18. This shaft is rotatable in bearings 19 carried by the locomotive frame and has connected thereto la flexible shaft 20, which; is geared to "and driven by one of* the locomotive axles 21 by the gearing 22. This is only one of theimany ways whichvmay be i employed for operating the v governor shaft 13 and: it is understood thatany other suitable operating means may be employed. The arms of the: governor have i pivotally connected thereto, a member 23, *which isr slidable` on `the `shaft 13, "when i. the 1 governor is'` actuated and: pivotally `secured to i this member as is showni by24, `is onefendof the lever 25.` This leveris pivotallyvmounted upon `abraoket 26,fandits endwlrich is connectedto the member 23isiheld1normally depressed i by `means `ofua spring 27, while the opposite end of this lever has connected thereto one end ofa rod 28. This rod eX- tends upwardly `through the *locomotive frameI and islprovided with a rack 29, for engagement with ai pinion `30, the latter `also engaging rack teeth 31` formed upon ahorizontally movable rod 32. This last mentioned rod `lis` connected `with valve 33, which is included in` the steam line 534 ofthe locomotive for i the purpose i of f controlling the steam tothe engine,iso1that wheirthe governor is `actuated to' move the member 23 upon-the shaft, the rod 38 will operate? the pinion 30 and through the rod `32 will close the `valve in a degree `proportionate to the movement of? the member 23.

f For the purpose of holding the member 23 inits lowerposition against` the `action of the spring 27, and to maintain the valve 33 inopeni position, there is provided awedge shaped' member fand slidably connected toi this member isone end of a link 36 which passes upward through the lever 25 and spring 27 andhas itsuppler `end engaging the upper end oflthe spring. `{["heflower end of the link 36 isI arrangedfor operative engagement with the inclined under surface of the wedge shaped member 35 so that when the latter is moved horizontally in a direction away from theagovernor shaft` 13,

`ico

Q substantially U shaped members 59.

the tension on the spring 27 is released and the member 23 permitted to slide upon the shaft 13.

The wedge shaped member 35 is connected to one end of a rod 39 which is slidable in bearings 40l secured to the frame of the locomotive. The opposite end of this rod is provided with teeth 4i which are engaged by a pinion 42, mounted upon a shaft 43 disposed transversely of the locomotive. This shaft also has secured thereon aV gear 44 whichis engaged by a worm 45, the latter being'mounted upon a longitudinally disposed shaft 46. Secured to the opposite end of this last mentioned shaft is a gear 47, which engages a worm 48, the latter` being mounted upon a shaft 49 arranged transversely of the locomotive and rotatable in bearings 50. The shaft 49 is located inadvance of the steam cylinders 5l of the locomotive and is also vmounted in bearings 52 which are carried by brackets 53. These brackets also provide bearings in which are slidably mounted vertically movable rack bars 54, one of these bars being located upon opposite sides of the locomotive. The teeth of the bars 54 engage pinions 55 secured with each end of the shaft 49, so that the vertical movementrack bars 54 will rotate the-shaft 49 and through the gears 47 and 48 will operate the shaft 46 so as to impart a sliding movement to the rod 39 vthrough the gears 42 and 44 and 45. The lower ends of each of the rack bars 54 have secured thereto outwardly and laterally projecting rollers 56. Y

The track device ll which is designed to be engaged by the rollers 56 for imparting a vertical movement to the rack bars 54 may be located at suitable points along the track, for example at the `end of a signal block for the purpose A`of operating the locomotive carried device `to stop the train in the event ofthe signal being set at danger, or the said track device may be located in advance of a dangerous curve, bridge, or railroad crossingy to control the speed of the train at these points.

This trackdevice which may be located upon one or both sides of a track, includes an adjustable controlling member 57. This member comprises spaced parallel bars 58 which are connected throughout their lengths by spaced transversely arranged he bars 58 have their opposed faces beveled as shown yat 60 so as to provide a flared mouth for the entrance of orne of the rollers 56. When the adjustable controlling bar is in the position shown in Fig. 5, the roller 56 will pass betweenY the bars 58 without imparting movement to the rack bar 54, the

height of the bar 57 being such as to permit of this passage. However, when the bar 57'v is in the position shown in Fig. 6 the roller 56 will enter the lower end of the said member, passing between the bars 58, being gradually elevated until it passes out at the opposite end of the member, the degree to which the controlling member is elevated determining the degree of operation of the steam valve as previously described. For the purpose of adjusting the controlling member 57, there is pivotally connected to each end of the said member, one end of a link 6l. The opposite end of this link is pivotally connected to ouie arm of a bell crank lever 62, whose opposite arm is connected to one end of a rod 63. The latter is in turn connected to a rack bar 64, which is engaged by a pinion 65 mounted upon the shaft of the motor 56. This motor is preferably of the electric type and its operation may be controlled by any desired means, for example its circuit may be closed by the operation of a block signal when the latter is set at danger. In the event of the track device being positioned at points remote from a track or other signal, the circuit may be manually closed to regulate the position of the member 57 so that the speed of the train will be automatically controlled in a uniform manner each time the train passes the trace device.

The bell crank levers 62 are mounted in governor, means for operatively connecting the governor with an axle of a locomotive, means including a pivotally mounted spring actuated lever connected to the governor' for holding the latter in an inactive position, a valve included in the steam line of the locomotive for controlling its operation, means connecting the governor and valve for operating the latter when the governor holding means is released and a track device for releasing the governor holding means.

2. A train controlling device embodying a governor, means for operatively connecting the governor with an axle of a locomotive, means including a. longitudinally slidable wedge shaped element for holding the governor in an inactive position, a valve included in the steam line of the locomotive for controlling its operation, means connecting the governor and valve for operating the latter when the governor holding means is released and a track device for releasing the governor holding means.

3. A train controlling device embodying a governor, means for operatively connecting the governor With an axle of a locomotive, means for holding the governor in an inactive position, a valve included -in the steam line of a locomotive for controlling its operation, means connecting the gover nor and valve for operating the latter When the governor holding means is released, a transversely arranged shaft operatively con nected to the governor releasing means, a vertically movable shaft operatively connected to the transverse shaft and a track device for operating the vertically movable shaft.

4. A train controlling device embodyinga governor, means for operatively connecting the governor with an axle of a locomotive, means for holding the governor in an inactive position, a valve included in the steam line of the locomotive for controlling its operation, means connecting the governor and valve for operating the latter when the governor holding means is released, a transversely arranged shaft operatively connected to the governor releasing means, a vertically movable shaft operatively con nected to the transverse shaft, a track device for operating the vertically movable shaft and means included in the track device for regulating the degree of movement of the vertically movable shaft,

5. The combination With a train controlling mechanism having means for controlling the operation of the throttle and means extending from the locomotive for operating the throttle controlling means, of a track device located adjacent the track in the path of the extending means for moving the latter to operate the throttle controlling means and means whereby the track device may be adjusted to regulate the degree of such movement to control the speed of the train.

In testimony whereof I have affixed my signature.
